I had a question regarding the math section in the GMAT. I guess this would apply to either PS or DS. If the problem states that there are two variables, x and y, but does not explicitly state that they are distinct, can we always assume that x and y can be equal? This has always created some confusion for me as I have progressed in my studes.
Thanks in advance for your responses.
Hi Shai82, just as Fig said, in general in math questions, unless something is explicitly stated as not being possible you should assume that it can be possible.
